Remote Sensor Temperature Calculation
Calculation method applied to temperature readings from the remote sensors to
determine a single temperature measurement value for cooling and heating
control.
Remote Sensor Temperature Air temperature as measured by remote sensor.
Return Air Over Temp Threshold Threshold value used in the [Return Air Over Temperature] event.
Return Air Over Temperature Return air high temperature event.
Return Air Sensor Issue The air sensor at the inlet of the unit is disconnected or the signal is out of range.
Return Air Temperature The temperature of the inlet air
Return Dew Point Dew point temperature measured at the inlet of the unit.
Return Humidity Out Of Proportional
Band
[Return Humidity] has exceeded the upper limit of [Dehumidification Proportional
Band], or has dropped below the lower limit of [Humidification Proportional Band]
], for an extended period of time.
Return Humidity Relative humidity measured at the inlet of the unit.
Server Class The general classification for this system

Shutdown - Loss Of Power - Event
Control
Enable/disable the activation of the [Shutdown - Loss Of Power] event. If set to
'disabled', the event will not be annunciated. This implies that the event will not
be placed in any active event list or in any event history list.
Shutdown - Loss Of Power - Event Type The event type for the [Shutdown - Loss Of Power] event.
Shutdown - Loss Of Power
System lost power. This event becomes active when the unit is powered on
following an unexpected loss of power. This event remains active for 90 minutes.
Smoke Detected - Event Control
Enable/disable the activation of the [Smoke Detected] event. If set to 'disabled',
the event will not be annunciated. This implies that the event will not be placed in
any active event list or in any event history list.
Smoke Detected - Event Type The event type for the [Smoke Detected] event.
Smoke Detected Smoke detected.
Supply Air Over Temp Threshold Threshold value used in the [Supply Air Over Temperature] event.
Supply Air Over Temperature Supply air high temperature event.
